What does 750 gold mean?

750 gold: properties, composition, price per 1 gram

750 standard is known in many countries, because gold products contain a large ratio of gold metal to other components. This figure is 75 percent, and only a quarter is formed by an alloy of copper, silver, palladium and other added materials.

It is known that gold alloy is characterized by softness, which slightly complicates its operational properties and leads to deformation of gold products. It is for strength that some components are added, this is especially true for copper and silver.

The use of gold has led to the emergence of different systems for determining samples (metric, spool, carat, lot); they may differ in different countries. The most popular are the use of the carat and metric systems. Thus, for the countries of the former Soviet Union, metric is typical, for the western regions, carat, while 750 gold is equal to 14 carats.

Main characteristics of the alloy

The common version of 750 is often used for gold jewelry. It even has its own name among gold standard jewelers.

The palladium ligature additive gives it the greatest value and value, and it also has a beautiful and soft white color. Nickel is also a common additive; it is a cheaper option and is often magnetized.

It is known that it is the ligature components that play an important role in the color scheme and quality of the product. If strength is needed for daily use, add silver and copper.

The disadvantage of 750 gold is that it is not resistant to corrosion, even though the noble metal generally does not oxidize.

The quality of samples is determined by the processing of materials itself. Often, to ensure the longevity of gold jewelry, the so-called “metal steaming” is used. In this processing option, the sample is characterized by additional strength and hardness, maintaining a presentable appearance and shine.

Where are gold products used?

Gold mining has a long history; the metal has always been highly valued and used for important needs: as money or unique status items.

Modern technologies are also giving impetus to working with gold alloy; gold processing in the form of forging and casting is becoming popular. Shades of yellow and white are used for products using carved techniques.

Often 18k gold serves as the basis for colored vitreous enamel. At the same time, it is imperative that the copper ratio in the alloy is up to 16 percent, so as not to spoil the brightness and quality characteristics.

But the main products made from 750-karat alloy are, of course, wedding rings.

The positive properties of these alloys: easy forging and fluidity, persistent resistance to chemical influences and the influence of a harmful environment, make it possible to use it for the production of measuring instruments, electronics, in the automotive industry, the chemical industry and medical equipment.

A popular option for using the alloy is to buy it for investing money - investing. These opportunities are added by a large amount of the most precious metal, as well as high-level liquidity. There are many alternatives: ingot, plate, decorative wire, all of them are stored in banking facilities, at interest. While maintaining its valuable characteristics, 750 gold gold price per gram is stable and does not fall with fluctuations in the foreign exchange market.

White gold alloy

An expensive and beautiful version of the 750 alloy is white gold. In terms of its components, it consists of a nickel or palladium alloy, in a significant proportion of twenty percent, the rest is silver.

An addition of platinum is also possible, but the cost of such a product will rise significantly. In addition, platinum cannot be an allergen, because allergy reactions often occur with an alloy, for example, nickel. All these components add more strength and hardness to the noble metal. Each of them, as a result, is displayed in white in the alloy.

Interestingly, 18-karat white gold has an additional coating, it is rhodium, which adds shine to the rather dull shade of the alloy, plus protection from mechanical damage and a beautiful blue shimmer, which is visible even in the photo. This coating loses its characteristics over time, it is advisable to monitor this and periodically repeat the procedure.

White gold also uses special production. Namely, the granulation technique. The patterns and ornaments on the jewelry are formed by small granules that are welded to a gold base. Compositions with diamonds are ideal for white gold. There is a noticeable resemblance to platinum products, but the price is more affordable. Experienced jewelers often use 750 for their meticulous work.

18k white gold is quite universal by all criteria. This option is suitable for all age categories, hair colors and skin tones. It can be combined with any color range of other alloys, which opens up new horizons of imagination and imagination, creating jewelry masterpieces.

Italian gold with purity 750

Separately, there is an alloy of 750 gold made in Italy. It can be white, yellow or pink.

The components of the ligature also include silver and metals, which provide color solutions. But the main difference that Italian gold has is the absence of a copper component. Accordingly, this option is more soft.

The production of such products takes place in its own original way. Additionally, they are polished for an irresistible and characteristic shine of the products. Such jewelry always looks elegant and subtle, and has a complex, unique design approach.

When this alloy is made, options with different colors are also allowed to be mixed at the same time. In general, contrast is a distinctive feature of Italian-made gold jewelry. Popular is the use of floral motifs with the addition of diamonds or other precious stones. Italian trends are spreading to jewelry all over the world, they are trendsetters, and many brands have gained recognition in other countries.

Analysis of the price category of 750 gold

A constant question for buyers is the cost of a gram of gold alloy at the time of purchase of products. So how much does a gram of 750 gold cost? Let's analyze the main factors that determine the price.

1. World indicators of the cost of the corresponding sample;
2. National Trends in State Banking Attitudes;
3. The consumption of additional decoration elements, the uniqueness of the jewelry work.

The price per gram today is about $35 - $40. In a pawnshop, 750 gold will cost 20-40% less than the market value, but even here you should take into account many nuances, the color of the product (yellow or white), the presence of precious stones, condition, appearance and others.

When purchasing gold jewelry made from 750 karat, it is important to properly monitor and care for it; this will prolong all the positive characteristics of 750 karat, and the jewelry will delight you with its beautiful appearance and presentability. The alloy is famous for its diversity; you determine the popular white gold, the yellow version or the choice of Italian manufacturing companies yourself, according to your aesthetic preferences.

750 gold: description and application

Today, many different alloys of precious metals are used in the world, among which 750 gold occupies one of the leading positions in the production of jewelry. Let's take a closer look at what these numbers mean and what other types of gold there are.

Since ancient times, people have been attracted to this precious metal. At first, it was just a material that was relatively easy to obtain and easy to process. But since native pure gold is very soft, there was no way to use it for the production of tools. People of that time noticed that yellow metal does not change over time, does not rust or deteriorate. Thus, it began to be used as a means of calculation. This is how gold became a symbol of wealth and success.

What types of gold are used in jewelry?

In order to demonstrate their financial status to everyone, they began to produce various types of jewelry from this precious material. Today people also try to adorn themselves with gold items, however, jewelry has undergone many changes. All jewelry has become more elegant and sophisticated, because due to the ease of processing, truly amazing works of jewelry can be created from aurum.

But the softness of the metal creates problems: thin threads and monograms made of pure gold will bend literally in the first days of use and the jewelry will immediately become unusable. This problem was solved simply: alloy metals were added, that is, those that transfer part of their properties to the alloy.

For example, 750 gold standard means that the alloy contains 75% pure metal and 25% impurities, in particular silver or copper. Both of these metals make the gold alloy strong and prevent it from bending as quickly.

This alloy is very popular in the world of jewelry, because it is much richer in gold than the common 585 standard, but is still strong and durable. The most popular additives are:

• Silver;
• Copper;
• Nickel;
• Palladium;

All these metals impart hardness to the alloy and also change the color of the product. Let's take a closer look at how the addition of various alloy metals affects the color of the final alloy.

ALLOY COLOR	Gold	Copper	Palladium	Silver
White	75%	0%	20%	5%
Light green	75%	6.3%	0%	18.7%
Green	75%	0%	0%	25%
Yellow	75%	10%	0%	15%
Sunny yellow	75%	12.5%	0%	12.5%
Pink	75%	16.7%	0%	8.3%
Red	75%	21%	0%	4%

How do different samples of precious metal differ?

In addition to the standard system that is familiar to us, there is a carat system in which 750 gold standard corresponds to 18 carat metal. In the carat system, 24 units of volume are taken as the basis, which constitute 100%. To roughly imagine the relationship between the two systems, you just need to look at the summary table below, which presents the main jewelry samples used at the moment.

Metric system	Carat system	Share of pure gold
999	24	99,9%
958	23	95,8%
750	18	75%
585	14	58,5%
583	14	58,3%
500	12	50%
375	9	37,5%

Gold standard 583 is not used today; instead of the outdated standard, gold standard 585 is widely used in our country. This transition was made in order to adapt to global standards and to be able to trade domestic jewelry products in foreign markets.

Despite the addition of alloying metals, 750 gold still remains quite soft, which means that jewelry made from such an alloy must be used carefully - they are easily scratched and very easy to bend. Although, thanks to the same softness, such products are easy to solder, and creating jewelry from this gold does not present any problems. This is probably why jewelers all over the world are so fond of the 750 standard.

By the way, this type of alloy is ideal for products with enamel. In other samples, the coating may fade and lose color, but 75% gold allows the enamel not to change its properties for a long time. The amount of copper in the alloy is important here - it should be no more than 16%, otherwise the appearance of the enamel will still suffer.

How not to make mistakes when choosing jewelry?

If you decide to purchase a piece of jewelry for yourself, then you should only contact jewelry stores of large, reputable chains. This will allow you to avoid deception and forgery, when either low-quality gold or even costume jewelry is sold under the guise of gold products. If you nevertheless decide to buy from your own hands, or in a small shop, it is worth remembering a few points:

• The product must have a stamp stamped on it;
• There should be an assay mark near the hallmark numbers;
• The seller must have all the documents for the product confirming its authenticity;

Today, the standard hallmark in Russia is a woman in a kokoshnik, looking towards the hallmark numbers. Branding is done either by conventional extrusion or by the more modern method of laser engraving. However, it is worth remembering that laser engraving may become worn out during active use of the product.

Fraudsters often offer various alloys that do not contain gold at all under the guise of 750 fineness. The most common of them are aluminum bronze, goldine, mosaic gold, as well as tombac and platinum. An inexperienced buyer will not be able to distinguish a genuine precious metal from a fake by eye, no matter how hard he tries. This is why we advise purchasing gold only in serious stores.

How can you save your capital using gold?

Many people know that gold is a very liquid metal. Often people invest their savings in gold to save money over time.

However, you need to remember: this type of investment makes sense only when buying bank bullion, and in no case will save money if you buy jewelry. At a bank you pay for metal, while at a jewelry store you pay for the work of a craftsman.

If you need to sell the product, you will receive for it, at best, a third of its value - the price of scrap gold. Thus, investing in jewelry is a loss-making endeavor.

750 gold standard - what is it? How much does 750 gold cost?

If you look at the periodic table of Mendeleev, then gold is a heavy metal of a yellow hue with atomic number 79. In Latin it sounds like aurum. 750 gold – what does it mean? Where is it used and how much does it cost?

Uses of gold

According to historical information, gold is the pioneer metal with which humanity interacted. Acquaintance with him took place 2-3 thousand years ago, as evidenced by the jewelry found at the excavations. There are also references to this precious metal in the Iliad and the Bible. Gold also aroused great curiosity among alchemists, who often sought ways to transform metals into precious metals, which were credited with great power.

In the modern world, gold has several functions:

• in commodity production it performs the function of money;
• in art it is used for jewelry work;
• in medicine it is used as components of some drugs;
• also used in the chemical industry and electrical equipment.

750 gold – what does it mean?

It is worth noting that pure gold without additives simply does not exist; there is always some percentage of certain impurities present. The number of parts of pure metal contained in 1000 parts of the alloy is called fineness. There are 4 standard systems used in the world: spool, metric, lot and carat. The most popular are metric and carat.

In our country, the metric system is common, that is, the ratio of the number of grams of gold per kilogram of jewelry alloy. There are hallmarks from 375 to 999. 750 hallmark gold is most valued by lovers of expensive jewelry.

European countries and the United States have a carat system. The fineness in carats is the ratio of the number of shares of pure metal from 24 parts of the alloy. This system is intended exclusively for gold alloys.

585 or 750 gold?

Most often, when purchasing jewelry, consumers are faced with 585 and 750 samples. Russian lovers of precious metals often give preference to products with 585 fineness, which is easily explained by the price-quality ratio. However, jewelry made from such gold contains more impurities.

Gold itself is a very amorphous metal, and with constant wear, the product could become deformed or scratches could appear on it. By adding silver, palladium or nickel, zinc and copper, a harder precious metal alloy is obtained. 750 standard gold contains 25% of additives such as platinum, silver, palladium, copper and nickel.

Depending on the increase in the proportion of certain components, it is possible to obtain an alloy of various shades: from soft pink to greenish. It can be noted that in Russia the most common shade of gold is reddish, and in Europe it is yellow. The famous “red gold” is made by adding copper to a jewelry alloy. When the ingot is heated, it produces a unique reddish tint.

750 gold is special in that it is easy to polish and process. The most complex and sophisticated jewelry is made from this alloy. In addition, this gold can be used as an excellent base for enamel. Precious products of this type are now gaining increasing popularity.

But it is still worth noting that 585 gold is more suitable for everyday wearing of jewelry, as it is more durable. If we compare how much gold costs 750 and 585, then a gram of the first alloy is almost 1.5 times more expensive (the price is approximately 1,100 rubles).

Quality of gold products

Gold has a chemical ability: in its pure form it is not subject to oxidation and many other chemical influences. But when combined with other metals, these properties become different.

It is generally accepted that gold alloys of purity 750 and higher are subject to little corrosion. It is worth noting that when producing an alloy, gold may be distributed unevenly, and then the area in which there is little or no gold may be corroded.

The jewelry in this place will be dull.

Italian gold

Many reputable jewelry stores offer products made from “Italian gold”. The name, as you might guess, comes from the country of origin of the jewelry. Jewelry of this type has a special type of processing. They are carefully polished, and visually the products seem to shine. In addition, the jewelry is distinguished by fine workmanship and a variety of ornaments.

When purchasing such a product, you should pay attention that scammers can pass off a product of lower quality as Italian 750 gold. Real Italian jewelry must have an appropriate certificate. The Russian eye is unfamiliar with the colors of Italian gold, which can have white and yellow shades.

Italy is a unique country. It occupies an honorable third place in the world in the production of jewelry with gold mining of no more than 100 kilograms per year. The rest of the material is purchased from South Africa. Thanks to the unique design, profits from the sale of jewelry bring considerable income to the Italian treasury. Buyers of Italian jewelry are Switzerland, the USA, China, the United Arab Emirates and other countries.

White gold

18k white gold is an alloy of gold with nickel or palladium. Sometimes platinum may be present. The white gold alloy itself has a rather dull shine. To make it brighter, a thin rhodium plating is used, which, if the jewelry is worn frequently, must be renewed quite regularly.

The typical work technique used when making jewelry is granulation. Tiny granules are welded to a very thin gold plate, and with their help, a pattern is created on the product. This type of technology dates back a long time, as evidenced by historical and scientific excavations.

Currently, many lovers of precious jewelry have heard of such famous jewelry houses as BULGARI, DIMIANI, which use the granulation technique.

When purchasing gold products, you should pay attention not only to the price, but also to the availability of the necessary certificates and passports. It is worth purchasing products from trusted and well-known manufacturers in specialized stores.

750 gold

Gold jewelry has different prices depending on what brand is on the product. What is the difference between metals with different hallmarks and what properties does jewelry with hallmark 750 have?

Gold fineness value

The main feature of pure gold is its softness. It is this that makes the metal unsuitable for making jewelry, since any mechanical stress can be detrimental to the product. Gold easily loses its shape and leaves dents and scratches on its surface.

To extend the life of jewelry and protect it from damage, special gold alloys are used in jewelry. In addition to gold, they contain special alloying substances that give the product the necessary properties: ductility, hardness, wear resistance.

The sample of a metal indicates its amount in the alloy. Fineness is a three-digit number that represents the content of the base metal in one thousand parts of the alloy.

Features of 18k metal: properties of white and yellow gold

The number 750 means that the alloy contains 750 parts of gold and 250 alloying substances. If we convert the sample into percentages, then the content of gold metal and impurities will be 75 and 25%, respectively.

Platinum, palladium, nickel, silver, and copper act as impurities for gold. Their ratio is regulated by the state standard. These substances give not only different properties, but also different colors.

• The predominance of platinum or nickel in the alloy makes it possible to obtain white gold; a large amount of copper gives a red tint.
• To make ordinary yellow gold, combinations of these substances are used in almost equal proportions.
• A unique greenish tint is obtained by adding silver.

Palladium gives the product hardness and strength, and copper gives it ductility. At the same time, the presence of a large amount of gold makes the alloy quite soft compared to 375 or 585 gold.

Occasionally it is required to obtain a gold alloy with high hardness. In such cases, they resort to the method of floating metals. During the steaming process, the solid solution disintegrates, releasing the AuCu3 compound.

The gold alloy itself is resistant to any chemicals. Even in aggressive environments it does not lose its properties.

The only enemy of gold is aqua regia. This is a combination of concentrated nitric and hydrochloric acids, taken in a ratio of 1:3. In this compound, gold melts completely.

750 gold is also resistant to thermal influences. Even with repeated heat treatment, the structure of the metal is not damaged and cracks do not appear inside it.

Jewelry

In jewelry, 750 gold is considered a kind of gold standard. Expensive jewelry with precious stones is made from it. The method of carving a gold product is often used. One piece of jewelry can combine 750 gold alloys of different shades: pink with yellow, white with yellow, white with red, greenish with white.

Expensive crystals are used as inserts for rings, pendants, and earrings: diamonds, sapphires, topazes, rubies, emeralds. Amethysts, garnets, and zircons are used less frequently.

How much does 1 gram cost?

The price per gram of 750 gold is within 1,400 rubles. The cost of jewelry depends on the complexity of the work, the cost of metal and the price of stones.

Caring for gold items

Due to the great softness of gold jewelry with the hallmark 750, they require especially careful handling. The products must not be subjected to mechanical damage, so it is recommended to remove them when performing any work. To add shine to a ring or pendant, simply wash it in soapy water and rub it with a soft brush or cloth.

750 gold is in the category of expensive jewelry metal. Unlike the common 585 standard, it is used to create more sophisticated jewelry, the purchase of which is always a profitable investment.

Pros and cons of 750 gold products

Noble metal in its pure form cannot be used either to create objects of beauty or for industrial needs. High purity gold is overly elastic and brittle. Alloy additives are needed to give the metal hardness and the necessary ductility.

750 gold is considered ideal.

Measuring the purity of a precious metal

Gold hallmark - what is it? Breakdown is a system for measuring the volume of pure metal. It can be metric, carat, lot or spool. The metric standard determines the volume of pure gold in a thousand parts of the alloy and is marked with the corresponding numbers: 375, 500, 583, 750, 950, 999. In gold of the 750th standard, the noble metal makes up three quarters, the rest comes from various alloy additives.

In Western countries, the amount of pure gold in an item is measured in carats. The basis is not 1000, but 24 parts of the alloy. Labeling also depends on the percentage.

How do the metric and carat systems compare?

CaratMetricPrecious metal percentage (percentage)

24	999	99,9
23	958	95,8
18	750	75
14	585	58,5
14	583	58,3
12	500	50
9	375	37,5

Thus, 18 karat gold is similar to 750 gold.

Benefits of 750 sample

Craftsmen all over the world prefer 750-carat metal and call it the gold standard for jewelry. Compared to other alloys, it is better processed, which allows you to create chains, bracelets, rings and earrings from gold of incredible beauty.

In addition, jewelry connoisseurs of 750 gold are attracted by the high percentage of pure element.

What other advantages does this gold alloy have:

• it is most resistant to any type of corrosion and aggressive environments;
• has excellent malleability and fluidity;
• able to retain color and shine for a long time;
• Suitable for the manufacture of complex jewelry and technical designs.

How much does 750 gold cost? Due to its high purity, it is not very cheap. The price depends on the composition of the ligature and on market quotes. In 2017, it averaged 1,700 rubles per gram. Of course, jewelry is more expensive, because the work of the craftsman, the cost of inlay and the markup on sale are also assessed here. Additionally, a high density index affects the weight, and its price also depends on the weight of the jewelry.

Effect of ligature additives

The ligature options for 750 gold are varied. This could be copper, silver, nickel, zinc, even precious palladium and platinum. Each component brings unique qualities to the composition.

To give strength, copper and silver are added to the alloy. If the product is decorated with colored enamel, the copper content should not exceed 16 percent.

This additive can make the enamel dull. Also, gold with a large amount of copper can darken slightly over time.

Not only the quality, but also the color of the alloy depends on the alloy:

ShadeVolume of ligature (in percent)

Copper	Silver	Palladium
Light yellow	10	15
Bright yellow	12,5	12,5
Green		25
Pale green	6,3	18,7
Pinkish	16,7	8,3
Red	21	4
White		5	20

To create the desired shade, jewelers adjust the amount of one or another additive. White 18k gold items will acquire a bluish shine if they are plated with rhodium. The decoration becomes stronger, but the coating will have to be renewed periodically.

Palladium, zinc, nickel and platinum give the now fashionable white shade. The first and last components are very expensive, but such alloys are still cheaper than pure platinum, and are in no way inferior in quality. The white tone perfectly emphasizes the beauty of diamonds; such jewelry becomes real works of art.

Use of noble material

750 gold standard makes it possible to use the precious metal in measuring instruments, medical equipment and electronics. It is used to produce ingots for storage in jars, decorative wire and plates for lining various surfaces. But it is most widely used in the creation of jewelry masterpieces.

Complex work, for example, making designer jewelry from precious wire or a relief punch with strong pressure on the surface, can only be done from 750 gold.

The density of the composition encourages creative experiments: luxury decor items are made from such a noble metal.

To improve performance characteristics, alloys are produced using the “metal steaming” method. Thanks to this technology, strength and hardness are achieved. For a softer structure, additional processing is required.

World-famous designers (for example, Gucci, Armani) create stunning collections from soft Italian gold. It can be pinkish, white or yellow, which is used by craftsmen to play on contrasts.

Caring for decorative items

The noble base in jewelry does not require any serious care. But additives, especially non-precious ones, can lead to a loss of exquisite beauty over time. Jewelry loses its shine, darkens, and acquires a dirty green tint.

To avoid this, you need to properly care for your jewelry:

1. Do not engage in sports or other physical activities “in full dress.”
2. Remove rings and bracelets when performing household work - washing dishes, cleaning, laundry, when visiting a bathhouse or taking baths with additives (mineral, aromatic, radon).
3. Avoid contact with chemical compounds containing chlorine and active oxygen, as well as mercury.
4. Periodically wipe with a soft flannel to remove sweat particles.

White and yellow gold will regain their natural shine if polished with a piece of felt or wool with Goya paste. Dark stains from iodine are removed with hyposulfite. The product should be kept in it for about 20 minutes, then rinsed under the tap.

It’s easy to get rid of dark plaque with onion juice. It is applied to the surface and left for a couple of hours, then the decoration is washed and wiped with flannel. A composition based on ammonia and baby soap also helps against dark spots. You need to keep the jewelry in it for no more than a quarter of an hour.

Decorative items should be stored in a box with a soft inner surface. It is desirable that it has compartments for different types of jewelry.

The storage should be located in a room where there are no serious changes in temperature and humidity. Items with inlay require special attention, because each stone has its own storage features.

It is worth noting that jewelry marked 750 requires more gentle handling than jewelry marked 585. Due to the larger amount of noble metal, the 750 alloy is inferior in strength. In addition, such products are usually more elegant, more intricate, and more expensive.

Composition of 18k gold

The alloy of this sample is 75.5% pure gold, the remaining 24.5% is alloy, these are various additives. We can list several additional metals that are included in the composition of 750 gold:

• palladium (Palladium),
• nickel (Niccolum),
• silver (Argentum),
• platinum (Platina),
• copper (Cuprum).

Thanks to the presence of these elements, 18k gold can acquire different colors and shades: white, yellow, greenish, red, pink.

The strength of gold is enhanced by palladium (noble metal) and nickel (base metal). Gold with palladium takes on a soft white hue. Jewelry with palladium is more expensive and is purchased only by true connoisseurs. The cost of working with nickel is lower.

Sometimes copper is also used as an additional element: it gives the alloy even greater hardness. Thanks to it, gold acquires a pleasant pink or red color.

When silver is included in an alloy, gold acquires a slightly greenish tint. This alloy is also quite strong.

Yellow gold

Yellow gold is also usually 750 fine. It is very popular and is popularly considered a symbol of love and family warmth, which is why 18k yellow gold is used, for example, in the manufacture of wedding rings. Yellow gold is also a traditional symbol of wealth and power.

The composition of 18k yellow gold includes: 10% copper and 15% silver.

Europeans prefer white or yellow gold to red.

Products made of 18-karat gold

Forging gold of this standard is quite simple. Jewelry made from 750 gold is considered the most exquisite and sophisticated. All kinds of jewelry are made from this alloy: earrings, rings, brooches, cufflinks, clips, bracelets, pendants, etc. Quite often, precious stones are used in products: diamonds, emeralds, sapphires, beryls.

750 gold can also be used as a base for colored enamel.

The cost of 750 gold

To find out how much 750 gold now costs, you need to find out the cost of 1 gram of this precious metal. Today the price of 1 gram is 2127 rubles. This is the rate of 750 gold in Russia (see chart 1). But when calculating the total amount, one should take into account not only the cost of gold by its weight, but also the costs of sale, the cost of the services of a craftsman, designer, etc.

In Russian jewelry stores, the price of 750 gold is 4,700 rubles. for 1 gram. The cost of 1 gram of jewelry itself largely depends not only on the quality and complexity of the work, but also on the specific manufacturer.

In Moscow pawnshops, the cost of 1 g of 750 gold is 1580-1900 rubles.

750 gold standard - what is it: price per gram, stamp, white, yellow and other colors

750 gold is most in demand among jewelers due to its advantageous properties, making it easy to process and polish.

Let's look at the main characteristics of this gold in more detail.

Composition and properties

What does 750 gold mean? First of all, the “750” indicator reflects the percentage of gold contained in the jewelry - in this case it is 75.

The higher the sample, the higher the percentage of this metal in the alloy. The remaining 25% in the alloy most often consists of copper, nickel, silver, etc. These metals give gold greater strength and, if necessary, give it the desired shade.

The high demand for 18k gold is explained by the fact that it:

1. Convenient to use. It lends itself well to processing and polishing.
2. Suitable for making jewelry of any complexity (including wedding rings).
3. Contains a higher percentage of pure gold.

However, it is these features that explain a number of disadvantages of this type of precious metal:

1. The softness of the material increases the risk of product deformation.
2. If worn frequently and without proper care, the product can be easily scratched and may lose its shine and attractive appearance.

Brand

The mark placed on a gold product must have a clear structure. Its mandatory components are:

1. Code belonging to the State Assay Supervision Inspectorate.
2. Assay certificate mark.
3. Designation of the direct sample (in numbers).

If we are talking about 750 gold, you will definitely find a clearly visible number 750 on the product.

Types and colors

The color of 750 gold depends mainly on the amount and type of impurities of other metals contained in it.

In particular:

1. The yellow color is achieved by introducing 15% silver and 10% copper.
2. The less saturated yellow color is explained by the presence of equal shares of copper and silver in the alloy (an average of 12.5%).
3. Greenish gold contains an admixture of silver (about 25%).
4. A paler green tint is obtained with an admixture of copper (6.3%) and silver (18.7%).
5. Rose gold contains a higher percentage of copper (16.7%) and a lower percentage of silver (8.3%).
6. Red gold contains 21% copper and 4% silver.
7. The white color is explained by the palladium (20%) and silver (5%) it contains.

Strength

Natural gold, free of impurities, is not suitable for working with it because it is a very soft metal that is easily deformed and susceptible to external influences. That is why, to enhance these qualities, all sorts of impurities are added to it.

750 gold contains a number of impurities that provide it with sufficient strength. However, compared to gold of a lower standard, it is more susceptible to external influences.

Application

1. The most relevant area in which 750 gold is actively used is jewelry. However, gold is also widely used in other areas.
2. The ductility and high malleability of the metal explains why it is actively used in industry for the manufacture of measuring instruments and other types of electronics.

Price

The price per gram of material is one of the key issues of interest to both manufacturers and consumers.

Aspects that determine its cost include:

1. The price set on the world market.
2. Gold prices set for the specified period by the Central Bank of the Russian Federation.
3. The monetary costs required to produce a product on an industrial scale.

The estimated cost of one gram today in Russia is approximately 1,660 rubles.

Advantages and disadvantages

1. One of the undeniable advantages of the 750 standard precious metal is that it, like its alloys , is extremely rarely used in mass production. It is much more often used to make single, designer jewelry from many jewelry houses. Jewelry made in this way, in addition to gold, includes rare alloys and precious stones.
2. Since the metal is very easy to process, products made from it can be distinguished by the richest and most varied carvings, allowing the jeweler’s talent to be most fully revealed.
3. The addition of certain impurities makes it possible to significantly expand the color range of the material , as well as provide the alloy with the opportunity to differ in its own unique qualities.

The main disadvantage of 750 samples is the high cost, which does not allow anyone who wants to purchase this product. However, they look much more expensive and sophisticated.

Comparison with 585

Comparing the precious metal 750 with 585, it is worth noting that:

1. 585 gold has a more favorable price.
2. A high percentage of impurities of other metals provide the 585 sample with higher strength and resistance to mechanical stress.
3. Also, a lower standard is distinguished by a wider range of colors.
4. However, despite the obvious advantages of 585 standard, it is worth pointing out that it is extremely rarely used for the production of expensive luxury products.
5. The high strength of gold with a high content of this metal also explains why it is difficult to process in cases where voluminous decorative work of increased complexity is required.

Care

Since jewelry made from 750 gold belongs to the luxury category , caring for them is quite complicated and includes several aspects that must be taken into account.

The interaction of the metals that make up the alloy with oxygen, carbon dioxide and other air gases often leads to a change in the shade of the product.

Also, soft metal is susceptible to deformation and mechanical damage:

1. It is necessary to limit the contact of gold jewelry with aggressive chemicals (including cosmetics, household chemicals, etc.).
2. When playing sports, it is best to remove jewelry (sweat particles on the surface can negatively affect their appearance).
3. To restore shine, it is recommended to polish the product from time to time with a woolen or felt rag (in addition, you can use Goya paste for these purposes).
4. Using onion juice also gives a good effect. You can rub the product with it and leave it for two hours, and after this period, rinse and wipe with a soft material.
5. A solution of ammonia and soap will also help remove stains and darkening. However, it doesn’t take long to keep the product in this composition – no more than 15 minutes.
6. It is best to store jewelry of this type in boxes with soft upholstery - this will minimize the risk of damage.
7. Decorations should touch each other as little as possible. To do this, they need to be stored in different compartments that prevent contact.

Reviews

1. The optimal sample for any jewelry. gold is high, the products look expensive and attractive.
2. Products made from 18-karat gold look great, but without rhodium plating they are very easily deformed , deteriorated and lose their original appearance.

750 gold ligature

A ligature is a combination of several elements in one alloy. The most common additives are silver and copper. Platinum and palladium, as well as various base metals, are also often used. For example, copper and silver “inserts” are made in order to adjust the shade of the material and give it certain properties.

If the sample contains both silver and copper, then as a result the jewelry will have higher strength indicators and will retain its original appearance for a long time. The latter two metals have a higher cost, and in their pure form they are incredibly rare. Extraction is complicated by many nuances, which leads to increased costs. These components are often included in the ligature when it is necessary to create 18-carat white gold.

Of course, the cost of the finished product in this case will be quite high. Not every person can afford such luxury.

Base metals are also used as complements to some alloys. And 750 gold is no exception. We are talking about nickel, zinc, brass and similar elements. The greater their percentage in the alloy, the lower the final price of the product. Such alloys are ideal for the production of exquisite jewelry.

The gold standard in question is positioned as the most in demand today. At the same time, one cannot help but note the rather high cost of this material. The addition of base metals leads to a reduction in cost, however, the characteristics of the finished product will decrease proportionally.

How much gold is in 750 gold

Note that the percentage of gold content in a 750-carat product should be slightly more than 75%. Here an error of three units is allowed in each direction. It is customary to make rings, chains, and various jewelry from this alloy.

750 gold is also used in the production of bank bars. A ligature with the same marking is often used in the form of a coating - tinsel.

This is not so common, since gold leaf often has 999 purity and is positioned as completely pure, free of any impurities.

The sample of gold in question is quite expensive in relation to the 585 alloy, however, it is much cheaper. For 1 g of precious metal marked “750” you have to pay about $40.

However, in practice, it is unlikely to be possible to buy it for that kind of money - the price for most 750-carat jewelry starts at 2000/1 g and above. The cost is always formed by taking into account numerous factors.

For example, not only the cost of the alloy is taken into account, but also the price of its processing by a jeweler.

Properties, shades and rules for caring for 750 gold – Glitter Gem

750 gold is most in demand among jewelers due to its advantageous properties, making it easy to process and polish.

Let's look at the main characteristics of this gold in more detail.

750 standard gold, what is it, Italian gold

Nowadays, 750 gold standard is becoming more and more in demand, because it complies with GOST and is ideal for creating various jewelry.

What is 750 gold?

Pure gold is practically never found in the jewelry industry, since the obligatory presence of impurities often improves the initial characteristics of the precious metal. In this case, the breakdown of gold is usually called the number of parts of pure metal and its ratio with the alloy used.

The two systems used to value gold have gained the most popularity: metric and carat. In Russia, the metric system is successfully used, which assumes the ratio of the number of grams of gold per kilogram of jewelry alloy. At the same time, it is customary to divide the precious alloy into samples ranging from 375 to 999. It is important to note that 750 gold is successfully used to produce expensive jewelry.

In Europe and the USA, they use the carat system, which assumes the ratio of the number of shares of pure gold from 24 parts of the alloy. It is important to note that the karat system is only used for gold.

What sample: 585 or 750?

In many situations, a comparison is made between 750 gold and 585 gold. Which alloy still turns out to be the best in terms of visual and quality characteristics? It is almost impossible to give a definite answer, but at the same time, an increase in gold in the initial composition of any jewelry contributes to an increase in price due to the precious metal.

Many Russians choose 585 alloy, as it is pleased with its high quality and affordable price. At the same time, a large number of impurities are allowed that affect the appearance and characteristics of the decoration.

It is important to note that gold is an amorphous metal, which with constant wear could cause serious deformation and numerous scratches. The slightest addition of silver, palladium, copper, zinc or nickel helps impart hardness. At the same time, 750 gold always contains up to 25% additives, guaranteeing the best quality of any jewelry.

The final appearance depends on the availability of additional components. Gold can acquire both a soft pink and a greenish tint. It is important to note that Russians often prefer a reddish tone, while Europeans prefer yellow. Red gold, which has gained popularity in Russia, can only be obtained by adding copper. If gilding is provided, the appearance of the decoration always corresponds to the classics.

An alloy marked 750 always pleases with ease of processing, thanks to which you can count on creating the most complex and extraordinary jewelry. At the same time, jewelry is only suitable for going out. Everyday wear still requires the use of 585 alloy, as it is more durable. It should be noted that 750 standard always costs more than 585, and the difference in price reaches 1.5 times.

What ligature is used for gold alloy marked 750?
GOST defines the metals that are used for gold alloy 750. In this case, the shade that is purchased can be almost any. Moreover, the ligature determines the change in the technological characteristics of the precious alloy.

The inclusion of silver and copper in the alloy increases strength. Moreover, even repeated heat treatment will not lead to the appearance of even the slightest crack in the composition. In this case, silver gives a greenish tint, and copper - from pink to red. Taking these features into account, jewelry factories try to use copper or silver to be included in the gold alloy.

Interesting variations

Italian gold is one of the most unusual offers. Jewelry stores with a special reputation emphasize these offers.

You can guess that Italy contributed to the emergence of a special type of gold processing, which is necessarily polished and begins to sparkle more. In addition, jewelry is often attracted by its fine handmade work and exquisite ornaments.

In order not to fall for scammers, it is advisable to make sure that you have a special certificate for jewelry products.

750 white gold has gained particular value. In this case, the manufacturer may include nickel or palladium. The use of platinum is occasionally permitted. Most often, the gold alloy acquires a dull shine. To add extra brightness, a thin rhodium plating is used, which can be renewed regularly. Often, when making such jewelry, small granules are used, which make it possible to apply an exquisite pattern on the jewelry.

The cost of a gold alloy marked 750

How much does 750 gold cost? To calculate the price of gold, use the formula:

0.75 * Central Bank rate for the current date

The initial task is to determine the value of one gram of gold. The average price per gram will be 33 dollars and 70 cents. However, the cost of the finished jewelry is calculated not only taking into account the gold alloy with ligature and weight, but also taking into account additional characteristics.

750 standard, used to create sophisticated jewelry, adds to the price due to the following characteristics:

• master's work;
• design services;
• cost of natural stones.

Moreover, even the costs of transporting and selling jewelry products are taken into account. In this regard, most often the cost of finished jewelry starts from 2,400 rubles. At the same time, 585 sample costs from 1300 rubles.

It is important to note that repurchase leads to increased risks, since fraudsters can pass off jewelry as an ordinary metal alloy. To do this, it is enough to skillfully process the alloy. If a gold-plated alloy is used, suspicions may not arise. Only outdated or low-quality jewelry is available at low prices.

The cost of gold jewelry can only appear in one of two directions: a constant indicator (stability) or growth (increase in price). In this regard, 18k gold may be a worthy investment option.

The most important task is not to fall for the bait of scammers who may pass off other metal alloys as the product variant of interest.

If, however, the buyer of gold falls for scammers, the purchased jewelry will not have a real estimated value and, most likely, will not be able to last for a long time.

It should be remembered that gilding skillfully diverts any suspicion from fraudulent realities.

Legislation for 750 markings

Russian authorities regulate at the legislative level the testing and marking of precious jewelry. In this regard, 750 gold must have a unique marking, a state hallmark. Such designations confirm the fact that the precious gold metal corresponds to the specified standard. The marking is controlled by the Federal Assay Supervision to combat intruders.

It is also recommended to have a jewelry factory mark, but this requirement is only available for domestic enterprises.

In the 21st century, 750 gold alloy will continue to be the price for both jewelry lovers and investors.

750 gold standard: what is it, price per gram today, types and differences from other metals

Pure gold is 999 fine. It is so soft that if desired, the metal can be kneaded like plasticine. Precious metal of such purity cannot be found in nature. It is purified industrially and formed into ingots. It is impossible to use metal in its pure form to make jewelry, because products made from it quickly lose their shape.

750 gold - what is it and how does it differ from other samples? What dilutes the purity of the metal? How does this affect the properties and strength of products? Why is 750 more expensive than 585? Is yellow gold white? Does it turn black and why? You will find answers to these questions and other interesting facts about the precious metal in this article.

What kind of sample is this

The sample system was introduced to indicate the quantitative composition of the alloy. To improve the physical properties of gold, it is mixed with other precious and base metals. And the concept of “sample” means how many units of pure metal are contained in one thousand units of the alloy. This means that 750-carat gold jewelry contains 75% gold (18 carats according to the karat system).

Alloy shades

The color palette of 750-karat gold products is varied - from yellow to red and even green. The table shows the proportions often used in jewelry production to obtain a particular color.

Color	Gold	Silver	Copper	Palladium
Yellow	750	170	80
Red	750	40	210
Pink	750	125	125
Green	750	250
White	750	50	200

A higher percentage of copper gives a rich red tint. White gold can be obtained by introducing nickel into the alloy instead of palladium. This reduces the cost of the alloy.

How is it different from gold 585

Low standard is stronger and more resistant to deformation. Jewelry of 585 standard is cheaper. Due to the increase in ligature, the color range of jewelry is more diverse. This is gold for everyday wear.

Expensive luxury jewelry, especially with precious and semi-precious stones, is made from 750 gold alloy. Such products have high liquidity. You can easily sell them to a jeweler or take them to a pawnshop in any country. If one of the purposes of the purchase is to invest money or preserve capital, then it is better to choose jewelry of a higher standard.

Application of this alloy

750 sample can be processed well when exposed to high temperatures. The alloy produces cast, relief, and link products. The main area of ​​application is the production of jewelry. High-grade gold is also used in industry. Wire and thin plates of 750 and higher standards can be found in measuring and other electronic instruments.

The alloy is used as a basis for applying multi-colored glassy enamel. The condition must be met - at least 160 units of alloy copper. The alloy is flexible enough to produce complex filigree and relief patterns.

How much does a gram of 750 gold cost?

Prices depend on several factors. The cost of 1 gram is determined based on the cost of pure material, as well as the cost of producing the product and its design value. The final price of a gold product includes overhead costs - the seller’s salary, the rental of a retail outlet, and hallmarking. The relevance of the price depends on the exchange rate of the world foreign exchange market and the Central Bank of the Russian Federation.

A new product of 750 standard costs in the store from 3000 to 4200 rubles per gram. Pawnshops and purchases accept jewelry at the price of scrap. Here are the current prices for today:

Recommendations for care and cleaning

Tips for maintaining the attractive appearance of gold jewelry:

• avoid contact with cosmetics and bleaching agents, especially those containing chlorine and active oxygen;
• remove jewelry while doing household chores or playing sports;
• protect products from mechanical damage;
• iodine is an aggressive medium for gold and forms hard-to-remove dark spots on its surface;
• You need to regularly clean the products from particles of dirt and sweat with a soft flannel cloth.

Polishing with a woolen or felt cloth with a small amount of Goya paste will help restore shine. Dark spots are cleaned with onion juice, a solution of ammonia and laundry soap.

Proper storage of jewelry is of great importance to maintain the attractiveness of jewelry. Gold should be stored in caskets, thick boxes with soft upholstery. Products should not touch each other, so there should be a separate compartment for each element.

Does gold darken

The darkening of the alloy is due to the oxidation of the alloy. Silver and copper interact with oxygen, moisture, carbon dioxide. As a result, silver turns black, copper turns green or black. The less impurities of base metals the alloy contains, the lower the risk of oxidation and loss of appearance of the product.

Metal can darken from frequent wear because it simply gets dirty. The risk group includes jewelry that comes into contact with the body - chains, earrings, wedding rings. Gray spots appear from exposure to iodine or mercury. The substances aggressively destroy the top layer of gold. It will no longer be possible to clean and restore the surface.

Why do gold items turn your fingers black?

First, the decoration turns black for some reason. From the darkened metal, the pigment is transferred to the skin. Factors that provoke this:

• poor quality of the alloy, deviation from the standard composition;
• polishing paste on the surface of a new product;
• allergic reaction;
• the use of cosmetics that contain substances that come into chemical contact with the ligature;
• pollution.

Appearance of gold streaks

According to popular belief, stripes on the skin under jewelry appear as a result of the evil eye. In fact, the darkening is caused by a common chemical reaction. For example, if cosmetic products applied to the skin contain traces of mercury.

Greenish stripes indicate an allergic reaction to copper in the alloy. The stripe on the skin can darken due to nickel. Amino acids in the human body can also react. Their interaction with the precious metal causes dark stripes to appear under the jewelry.

Tips for choosing gold jewelry

When choosing jewelry, the buyer is usually guided by the ratio of financial capabilities and visual attractiveness. Women choose more emotionally, trying them on and evaluating how much the product will decorate and emphasize their dignity. The choice of yellow, white or red metal depends on personal preference.

You should purchase high-grade designer gold items only in specialized stores. The quality of the alloy is guaranteed there. Before purchasing, you should pay attention to the stamp and permits. On a tray or from your hands, there is a risk of acquiring low-grade metal or even gilding. In terms of wear resistance and liquidity, it is better to choose 585 or 750 samples.

Yellow 750 gold has a very rich lemon color. Alloys below fineness are generally duller.

When buying high purity white gold, you should pay attention to the presence of rhodium plating. Without coating, the product will quickly darken.
